Both are great games that are a lot of fun. I see your current pin is a Batman 66 which is a very deep game. If you want another game that is as deep, actually deeper, then go with WOZ. WOZ code is not only extremely well polished but also incredibly deep. JJP is still adding making changes and additions to WOZ code 5+ years after release! In a two game collection and you mentioning wanting a pin with a deep ruleset I think MB will get old quick.
